Introduction

SPF (Sender Policy Framework) is an email authentication protocol designed to prevent email spoofing. It works by allowing domain owners to specify which mail servers are permitted to send emails on their behalf. This is done by adding a special SPF record to the domain’s DNS settings. When an email is received, the recipient’s mail server checks the SPF record to verify that the email is coming from an authorized server. If the server is not authorized, the email can be flagged as suspicious or rejected. SPF helps improve email security and ensures that legitimate emails are delivered while reducing the risk of spam and phishing attacks.
